I p JQSoI-iiulnurr, J r., a citizen gofthe UnitedV States, residing atChicago, in the county offyCook and State of Illinois, have'inventedcertain new and useful Improvements in Conveying System-s or the Like,of which the following is a de scription.

` My invention belongs to that', general class of deyiceslknoyvn asconveying lapparatus relates moreparticularly toa system Vor apparatusfor receiving f'inatferial andfdisthe same'tothe storage bins from whichit may be further distributed or` conveyed"byv gravity or any other'system or systems, to Where desired. lHowever, the device'is notlimited to the finateria'ls or systems' 1nen, "tioned but may be'k usedwherever foundap-- Aplicable and with all or parts of any-"other systemlor apparatus With/(vhich it maybe suitably used.` Vhen lapplied to coalsheds the usual tower may be omitt'edand there "beingno intermediatetransferringfrom the time the coal is'gloaded in the "bucket until it isdischarged in the storage bin `the coal is not broken' up as much norist-here as much dust.

To this endl my invention eonsistsin the novel construction, arrangementand combination of parts herein'shown and described 'and vmorel'particularly vpointed Yout vin the;y

In the preferred construction the bucket is hoisted to the topof the shaft or to the higher level by means of a cable 24 Which alsolaterallydraws thel bucket and carriage when the bucket reaches 2G thetop of the shaft. The cable 24 is secured tol the-bail 23 of the bucketand to a drum 25 driven by a suitable motor or, engine26 -or theequivalent, suitable pulleys 19 and 20 carried by the frame at points 2521 and 22 and a pulley 27 carried by the structure beingy preferablyprovided to guide the same. the bottom of the shaft by means of a cable50 orits equivalent which may be secured S0 directly to the drum 25 andcontrolled by therv'ersal of the drum or which may be arranged in amanner explained hereafter. Any suitable means may be employed tocontrol the discharge of material from the bin 5 tothe bucket 8 a chute28 provided with a shield 29 being shown for the purpose, theconstruction being such that when the bucket descends it pulls down thechute 2S discharging a bucketful into the bucket 4o the shieldpreventing more than a bucketful from :being discharged from the bin.Hoisting the bucket raises the chute 28 to be again filled the sameremaining closed until the bucket again descends. As the drum 25isrotated drawing cable 24 the bucket is hoisted until it reaches theposition substantially as shown in Fig. 3 (this figure showing thecarriage having started on its lateral movement). Thile over the shaftand until the bucket is entirely hoisted the carriageis held againstmovement by a suitable locking memberl 30 engaging the notch of thelcoperating locking part 31. Locking member 30 is pivotally secured tothe frame 55,-as'at1533andyisfoprated by a'rod 34 pivotj ally securedlAthereto at 35, which rodl is .operated by thelever 36 provided With anextended end 39. The lever 36 is pivotally secured to the frame at 37and to the `rod 34 at 38. A resilient member 341 is also pro- 'vided andarranged to resiliently retain the parts in operative position. When`the vbucket is raised until the bail 23raises the end 39, the catch 30will be disengaged from 654 the notch of part 31. thereby releasing theThe bucketmay be returned ,to'

carrier so that continued drawing of the cable 24 drawsthe carriagealong the tracks 7. Any equivalent arrangement for locking the carriageover the shaft When the bucket is down maybe provided. The carrier isalso provided With a suitablelever or lock 40 secured thereto as at 41which is provided with a notch 42 adapted to engage the edge 421 of thebucket While carried laterally by the carriage' the arm 40 being re- 75tained out of operative position by means of a stopV 32 carried by thestructure when the carrier is over the' shaft.

To open the bucket at the desired time so that it lWill discharge itscontents, I prelerably provide What'may be termed trips 44 carried bythe structure and arranged to engage the latches on each side of the`bucket so that they will release the bottom and permit the same todrop. As shown the 3 5 trips are preferably secured to the structure asat 45 and provided with suitable stops 47. Normally the trip 44 is heldagainst its stop bymeans of a weight 49 or its equivalent'arranged onthe extended arm A48, a 9- roller 46 may also be arranged as shown ifdesired. -As the carriage 9 moves over the' shaft the trips 44 arrangedWhere desired engage the hooks 15 substantially as shown by the dottedlines (Fig. 3) releasing the 95 bucket bottom, the trip swinging aboutthe center 45 on the return of the bucket permitting the hooks to pass.To close the bucket I'preferably provide a member 52 arranged Whereverdesired, as shown substantially near the elevator shafhwhich will forcethe bottom up in position where it will again be engaged by the hooks15. As shown the member 52' is pivotally carried by the structure as at53, the same being provided with a stop 54, and. suitable means such asa Weight 521 for drawingthe same back into position. vA Wheel 55 mayalso be provided if desired. Any equivalent arrangement of bucket andcontrolling or operating mechanism for the bucket may be provided.Before the carrier or carriage 9 reaches the. v end of itstravel towardthe shaft, the lever or bucket lock40 engages the stop 32 releasing thebucket so that the same is supported in the carriage bythe cable 24.When the carriage reaches the end of its travel the bucket descends, thecarnage being locked in position over the shaft. It might be noted thatduring the hoisting of the 120 bucketA as well as during its'lateralmovement ythe same is carried or supported by the carriage.

In the preferred construction I use two buckets and arrange the same sothat as one bucket is hoisted the other Will be retrieved to the loadingpoint, that is they work alternately. Referring to the diagrammaticview, Fig. 4,- 8 and 81 represent the two buckets andv 9 and 91 the 'twoframes. The 13C noie cable 24 `secured to bucket 8 passes over thepulleys i9 and 2G, over pulley Q7 to the drum Q Where it may be given anumber of turns` varound the drum and then extends over pulleys 271,201and 19I being secured to bucket 5G and 'being provided where desired.,As

is obvious thisl construction forms vsubstantially an endless cable madeup of the cable "24 and cable 50.l As the bucket 8 is-drawn up by meansof the cable 2e vthe hucketS1 y and the carriage 91 are drawn towardlthe loading' point. Vhen the bucket 8 reaches riage is drawn along'thetracks until `the other bucket reaches the bottom of the shaft, thetrips etal. foroperat-iiig the bucket being of course arranged in thetravel of the carriage at the pointlvvhere it is `desired to dischargethe load. It might lbe vnoted that 4the tracks over the shaft areslightly inclined in the preferred construction. `Then the carriagereaches the inclination'the tendency l is for the Weight of the carto'always carry it to the endof its travel. f f A Any suitablearrangement may be ein ployed'to control' the operation of the drum 25orto're'verse the same when a bucket reaches the bottom of the shaft, asimple arrangement being shown diagrammatically in Figs. 1,2 and 4c, inWhich the motor 26 driving the drum 25 is controlled by a suit-` ableswitch Soperated by a plurality of levers 59 and'tl1 or their equivalentarranged -in the path of the carriages. -These levers are suitablyconnected by means of cables 650-601 `or theirv equivalent -to theswitch S, 'suitable pulleys 6l being provided if required. Operating theswitch changes the polarity of the motor* thereby reversing the drum.Any equivalent arrangementmay be provided. as mentioned the arrangement'is suchthat the drum Will be 'autobottm-of the shaft andreceives itsload.,

There may be any number yof storage bins andV of course it is obviousthat the trips and binsmay be so arranged vthatone bucket Will bedischarged in one bin While the other bucket may be discharged in anyother bin.

Having thus described myv invention it is obvious that variousimmaterial modilicaltions may be-'made in the arrangement, constructionand combination of parts shown and described or that the same maybe usedWherever it may be found applicable Without departing from the spirit ofmy invenL tion, hence I do not Wish to be understood as limiting myselfto the exact construction, arrangement and combination of parts shown ordescribed or uses mentioned.
